Answer:
B, C, D, E
Step-by-step explanation:
I just substituted the pairs in so
14 = 6(3) - 4(1)
14 = 18 - 4
14 = 14 yes that works
let's try another pair just so you see
14 = 6x - 4y
14 = 6(-1) - 4(-5)
14 = -6 - (-20)
14 = 14 yes that works
14 = 6(1) - 4(-2)
14 = 6 - (-8)
14 = 14 yes that works
14 = 6(14) - 4(-4)
14 = 84 - (-16)
14 = 100 nope
14 = 6(4) - 4(2.5)
14 = 24 - 10
14 = 14 yes that works
